-REMOVABLE SEWER CATCH-BASIN.

Application filed September 13, 1915.

To all whom it may concern:

Be it known that I, HYMAN STEIN, a citizen of the United States, residing at Wabash, in the county of Wabash and State of Indiana, have invented certain new and useful Improvements in Removable Sewer Catch-Basins; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in removable sewer catch basins.

The object of the invention is to provide a simply constructed device of this character which may be placed in and readily removed from any ordinary sewer catch basin such as are usually formed at intervals in sewers for receiving sediment and the like.

Another object is to provide a removable sewer catch basin equipped with means for preventing it from sticking or being held by suction inthe stationary sewer basin in which it is disposed.

With the above and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts which will be hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 represents a vertical section of a sewer with the stationary catch basin formed therein, equipped with this removable catch basin disposed in operative position therein;

Fig. 2 is an enlarged rear elevation of the removable catch basin removed; Fig 3 is a central vertical section of the basin taken on the line 3-3 of Fig. 2 with the bottom shown in open position in dotted lines; Fig. 4 is a horizontal section taken on the line 4-4 of Fig. 2. r

In the embodiment illustrated, a removable sewer catch basin or cleaning basket is shown rectangular in form to adapt'it to a stationary catch basin B of. this form, al-

though obviously it may be of any otherdesired cross sectional contour according to the shape of the stationary basin in connection with which it is designed to be used. This removable basin or basket comprises four corner uprights or standards 1 shown constructed of angle iron and having their upper ends connected by cross bars 2 which are also formed of angle iron having their Specification of Letters Patent,

ends overlapping. Eye-bolts 3 extend through the overlapping ends of the cross bars 2 at the corners of the basket and thus perform the double function of additional securing means for connecting the cross bars and'as means forconnecting the chains d to the basket, said chains being designed to be used as handles for raising and lowering the basket and are here shown secured to a ring 5. This ring 5 is adapted to be engaged with a hook 6 of a hoisting apparatus which may be mounted on any suitable 1strtucture for raising and lowering the base Side plates 7 are secured to the standards l with the lower ends of said standards extending below the bottom edges of said enters the basket will extend over the topof the plates 7 and drop down into the stationary basin. The standards 1 extend some distance above the .top edges of theiplates- 7 and form a skeleton frame above said plates, which latter constitutes the body portion or sediment containing receptacle of the basin when taken in connection with the bottom 9 to be described.

As shown, a grating is formed at the discharge or outlet side of the basket, although obviously such a grating may be arranged on all sides of the basket except at the inlet thereof. This grating as shown, comprises a plurality of heavy wire rods 10 which have their ends bent laterally substantially at right angles and which are inserted through apertures in the upper edge of the rear plate 7 of the basket and in the depending flange 2 of the rear connecting cross bar 2 as is shown clearly in Figs. 1, 2 and 3. The ends of these rods 10 after they are inserted through the apertures in the plate and cross bar, are upset'to form retaining heads 11, whereby they are reliably held in engagement with the parts to which they are applied. "These bars 10 are spaced laterally apart any suitable or desired distance sufficient to prevent the passage between them of paper and similar trash and yet permit fluids to fiow freely therebetween.

The bottom 9 is hinged at one side thereof to the lower edge of one of the plates 7, be-

' tom 9 when desired for dumping the basket.

.This bottom 9 has an opening 13 here shown arranged centrally therein and aroundwhich is formed an-upstanding internally threaded collar 14 which is designed to receive the threaded ,lower end 15 of a suction breaking pipe 16 which extends *upwardly into the basket to a pointbeyond the normal water level in the sewer S in which this basket is designed to be mounted. While this pipe '16 is shown connected with the bottom 9 by means of its threaded engagement with the collar 14, it is to be understood that it may be connected therewith by any other suitable means, it being preferably detachable to provide for its removal when desired for cleaning or other purposes. This pipe 16 is designedto break the suction between the bottom 9 and thelower wall or bottom of the stationary basin B, permitting the air to enter under said bottom 9 and thus prevent the bottom from sticking or being held by a vacuum formed under the basket such as might be likely to occur on the removal of the basket were this pipe not provided.

In' the use of this removable basin or cleaning basket, the bottom 9 having first been closed, the basket is lowered through a manhole M disposed above the stationary basin B in which the basket is to-be mounted and said basket is lowered through the manhole into said basin B until the. feet 8 thereof engage the bottom of said basin, it being of course understood that the basket is so disposed that the grating'formed by the bars 10 will be arranged at the outlet or discharge end of the sewer, while the unobstructed portion thereof will be arranged oppositethe grating or toward that portion of the sewer through which the sewerage flows in the direction of the arrow shown in Fig. 1. After this basket has been placed in the basin B, it is allowed to remain untilthebody portion formed by the plates 7 thereof becomes filled or nearly so and it is then removed by engaging a hoisting apparatus with the ring 5 and thereby lifting the basket bodily with the contents thereof through the manhole M. After it has been raised from the sewer, this basket may be dumped either into any other suitable receptacleand the catches 12 may be actuated either manually or mechanically at the will of the operator, trips being preferably provided for this purpose so that the dumping of the basket will become automatic.

it is lowered into the basin B through the manhole M and is -again ready for use.

It is of course to be understood that the sewer S is provided as usual, with a plurality of stationary basins B arranged at intervals and which are disposed below the manholes M which afford access thereto and by equipping each of these basins B with one of these removable basins orbaskets, great secured to said uprights, said uprights projecting above and below said plates forming a After the basket has been dumped and the bottom 9 again closed,

standards above and feet below, cross bars I connecting the upper ends of said standards, a grating arranged on the outlet side of said basin between one of said cross bars and' plates, a hinged drop bottom mounted on said basin, a catch for holding said bottom closed, and means for engagement by a hoisting device.

2; A removable sewer catch basin comprising angle iron uprights, angle bars con-.

necting the upper ends of said uprights, side plates secured to said uprights and of a height substantiallycorresponding to the depth of the stationary basin in connection with which it is designed to be used, said uprights extending below the bottom edges ofsaid plates to form supporting feet, a downwardly opening bottom, hinged at one edge to the lower edge of one of said plates, a catch on another of said plates for holding said bottom. in closed position, wire rods engaged at their opposite ends with.v one. of

said plates and with one ofsaid uprightconnecting bars, the ends of said rods being bent laterally inward and extended through said plate and barand upset to retain them inoperative position, eye-bolts engaged with the flanges of said connecting bars, lifting chains engaged with said eye-bolts, and a ring connecting said chains.
